Cylinder Head Sensors

Hi all,

Can you help me identify the sensors on the top of the cylinder head please?

I know the one on the left is water temp, but unsure what the right one is. All the diagrams i have seen have this as a blanking bolt...

Many thanks

This is usually a blanking bolt yes. Im guessing someone added another Water temp sensor at some point? I presume one doesn't work. They both go into the water gallery so must be???

They are both water temp senders, there was a later one and an early one (on a 19j) , I seem to remember having trouble swapping my temp sender over during my last engine swap. Dont remove them until you get the new one and know what hole it goes into, the threads are different in both.
